Help with my dilema?????????????

If it were me Ed,and I do it to all my cars that have been on the tree shift ,go with the after market shifter you have.So easy to do.Note,if you do the after market shifter pre mock your bucket seat first, sit in it and adjust were your shifter will go you will want a nice grab on it.I have seen some guys just install it and find out they dont like the placement,also your cable leaving from the shifter for the first say 9 inches or so has to be very straight.Not sure what to tell ya on the hump.
